To ensure consistently high quality of a gas mixture, it is ensured before the filling process that the delivered cylinders are completely free of residual gases. To do this, the containers are evacuated before refilling: all residues from the previous atmosphere – such as residual gases, air, or moisture – are reliably extracted. This procedure is standard practice when filling Evacuating & Filling technical and medical gases. With WEH® quick connectors, this step can be carried out just as efficiently as the subsequent filling process. The connectors connect in seconds without screws and ensure...
